If this is the case what rule limits the size of the hole based on the objects it takes in.

Yes it does get bigger. But so does the Earth. I mean, when a meteor falls to Earth, it never flies back up, does it? People have this idea that black holes are somehow different because even light cannot escape their gravity. If light cannot escape, nothing else can either, so the black hole will eventually eat all the matter in the universe, right? Well, light can escape from Earth but nothing else can, at least not naturally. Meteors fall to Earth all the time and they have no rocket engines so they can never escape. This is true for any matter that falls to Earth. It can never escape. And the Earth is not eating all the matter in space, so why would you think a black hole would?

The size of the black hole is not determined by the size of some block of matter within it, but the size of the Schwartchild radius. Which is the event horizon where light can no longer escape. As the mass increases, the size of this radius increases.
The only limitation is the amount of mass in the universe.

Adding mass to a black hole increases the... well, the mass of the black hole. Greater mass results in the expansion of the black hole's EVENT HORIZON, which is the point beyond which nothing (for all practical purposes) can escape the black hole's gravitational pull.
In other words, larger masses result in stronger gravitation fields. It's no different for black holes.

When mass is added the mass of the black holes will increase. But the black hole is not a hole. All the black holes are spherical.
Most of the galaxies do have black holes at the center including our own milky-way

Until now the black hole is an abstraction, because nobody can tell with 100% of security that black holes exist. But, if you suppose that black holes exist it is possible that the total volume of them can become larger when new materials are swallowed by them.

black holes are not defined by "size" as in dimensions. They are defined by MASS
